Question

Hello fellow uniteres!

I have a third person game where the camera is free to rotate around when the player is not moving. And when the player is moving the players Y axis lines with the cameras Y axis, but when doing so the player "snaps" to the cameras Y axis.

I want to make this smooth and therefor considering using Quaternion.Slerp, but the problem using Quaternion.Slerp is that it is "Slerping" all axis X, Y, Z, but as said I only want to "Slerp" the Y axis. Is this possible(It most likely, but I do not know how to) I have tried Mathf.Clamp, but that causes "shaky" movements and slow fall through the floor.

The current code I use for the rotation right now is this(small sample only):

  var GameCam : Transform; //Camera goes here.

    if(Input.GetAxisRaw("Vertical") > 0.1 && !Input.GetAxisRaw("Horizontal"))
    {
    transform.eulerAngles.y = GameCam.eulerAngles.y; // This is used for the rotation
    transform.Translate(0,0,Input.GetAxisRaw("Vertical")/20);//Movement no need to look at that.
    }

So can you please tell me a way to restricting "Slerping" to the Y axis only. I will be greatfull!

yourRotationQuaternion = Quaternion.Slerp(to, from, time);

yourRotationQuaternion = Quaternion.Euler(new Vector3(0f, yourRotationQuaternion.eulerAngles.y, 0f));

done like dinner

Thank you. tried messing with it, but importunately the player only turns/rotates 0.8 degrees each direction and nothing more and then the player is kinda "clamped" there and can not rotate further.

You corrected Anxo, but you made the same mistake. yourRotationQuaternion.y is not an euler value so putting it into Quaternion.Euler is a mistake

Ah- yes. I've edited my post to clarify.

Just more proof that we need intellisense here too :)

transform.rotation.y = Quaternion.Slerp(bla bla bla).y;

yeah, but Y is not what you're thinking it is- he's talking about restricting to the Y euler angle, this would give you the Y quaternion component, which is not the same thing:

oh I guess I tried to answer the title without reading the question.

After the Quaternion.Slerp statment

transform.localEulerAngles = Vector3(0, transform.localEulerAngles.y, 0);
